TIME METER.

Specification of Letters Patent.

Patented May 2, 1922.,

Application filed March 18, 1921.' Serial No. 453,196.

To all whom it my concern:

Be itknown that I, RALPH E. BISHOP, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Time Meters, of which the following is a. specification.

This invention relates to. time meters and is designed primarily for use in determining the periods of time at which the run of a number of reels of picture films of a predetermined length will be completed, so that the operator may determine almost at a glance the hour and minute of the completion of each show during the entire day.

The prime feature of the invention is the provision of a stationary member having a scale of hours from 1 to 12 and fractional hours or minutes between each hour, co-

operating with which is a movable member having a chart or graduations thereon, which will indicate the number of reels of film being run during each show, these numbers being shown in multiple, together with graduations indicating the number of minutes required to run each film, so that by properly setting the movable member at the hour at which the show first starts the operator may determine when each show will terminatedur'ing the remainder of the day by noting 'the various graduations on the two members which may be done almost instantly.

Other objects and advantages will be hereinafter more fully set forth and pointed out in the accompanying specification.

In the accompanying drawings,

Figure 1 is an elevation of the device, and

Figure 2 is a central sectional view thereof.

Referring to the drawings, 1 indicates a body portion which is normally held stationary, said body portion having a circular space 2 on which is shown the hours from one to twelve consecutively, and associated with the space 2 is an additional space having graduations 3 thereon which indicate fractional hours, each of said graduations preferably indicating an elapse of two minutes of time.

Co-operating with the body 1 is a dial 4 which is preferably rotatably mounted by inserting an eyelet 5. through the axial center of the body and dial, although it will be understood that any suitable means may be provided for rotatably mounting the dial on the body.

The face of the dial 4 is divided into any specified film or reel, and said spaces 6 are subdivided by a plurality of radially extending lines 9, said lines 9 co-operating with the graduations 3 and the hour graduations in the space 2, the radial lines 9 having designating numerals, as indicated at 10 cooperating therewith.

In applying the device to use, supposing that the show begins for the day at twelve oclock noon, the radial divisional line 8 is turned until it registers with the numeral 12 in the space 2; then supposing that six reels of the conventional length constitute the entire show and that it requires eight minutes to run each reel, the hours and minutes of each show of six reels for the remainder of the running time may be very quickly ascertained by noting first the outermost space 6 on the dial after the dial has been properly set, and then reading the time at the outer end of each sixth numeral co-operating with the radial lines 9 in said outermost space. By this rule we find that the first show will terminate at 12 48; the second show at 1:36.; the third show at 2 24, and so on around the dial.

If twelve reels are being run for each show, which in most instances is the greatest number of reels that are allowed to be run at one time, and it requires twenty minutes to run each reel, the hours and minutes at which each show will terminate may be de termined by referring to the numeral indicated by 7 along the line 8, specifying the number of minutes required to run the reel, which in this instance is twenty, and then passing to the right on this space to' the twelfth radial line 9, intersecting the space 6 containing the numeral 20, we find that the first show will terminate approximately at four oclock, the second show at eight oclock, and the third show at twelve oclock p. m.

The same rule applies to any of the other spaces on the dial 4, the same proceeding being employed for determining the time at which each successive show will terminate.

This device can be very cheaply manufactured and will prove substantially accurate at all times, and while as stated, it is designed primarily for the use in picture theators in determining the time at which each show will end, it may be used for various other purposes, including vaudeville shows where different numbers are put on requir- 5 ing an approximate time for completing each number of the show.

Having thus fully described my said in. vention, what I claim as new and desire to secure by Letters Patent, is:

Means for determining the time required for running a designated number of picture film of a prescribed length, comprising a member having hour and minute graduations thereon, a rotatable member for cooperation with the first member having a plurality of circumferential and radial divisional graduations thereon, said circumferential and radial graduations having designating numerals for co-operation with the hour and minute graduations for successively determining the time required for running a prescribed number of films.

In witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana,

this 15th day of March, A. D. nineteen hum dred and twenty-one.
